RAILRVAEI CRQSSING STRUCTURE;

Application filed Mar-ch23. 1926. Serial No. $68.02.

' removable 1 tersecting plates which :may .be

conveniently replaced with a minimum amount of labor and obstruction of traflic.

A still further object of the invention is the provision of a structure of the above character which :is simple and 'durable in construction, efficient- "for the :purpose 'intended and which can be manufactured .at a comparatively low cost.

Other objects and advantages of the invention will become apparent as the description progresses.

In the accompanying drawings forming a part of this specification and in which like reference characters are employed to designate corresponding parts throughout the same:

Figure '3 is a transverse sectional view taken on the line-33-of Figure 1,

Figure rt :is a fragmentary perspective viewof the cross-over base structure,

.Figure 5 is a perspective-view of-the intersection rail plate, and

Figure 6 isan enlarged transver-sesectional view taken on the line 6-6 of Figure -1 As'willbe well'understood by those familiar with this art, railway track construction is subjected to unusual strain at the intersecting points due to the jumping of the train wheels over the crossing flange grooves, imparting repeated shocks to the rail structure. This results in rapid deterioration of the intersecting rails, necessitating frequent renewal thereof.

At the present time. it is customary to so constructthe rail structure that removable center pieces are provided at the intersecting points to permit renewal of the rails at the intersection. The existing structures devised for this purpose are defective and inefiicient, due to the impractical connection of the removable center structures and the supporting structure. lVith this in mind, my invention aims to provide a structure of greatly improved design, producing an apparatus which will be iighly practical and efficient and which will promote this art.

Referring with particularity to the Con struction embodying any invention, the numeral 1O designates in its entirety a crossing structure. the present embodiment illustrating'the formation of a single track crossing. This crossing embodies four intersect crossing sections comprising intermedi ate connecting portion-s11 and comparativelyshort-extending portions 12. The central portions of the sections are formed to provide a rail, .shown to advantage in FignreS. including a vertical web 18 formed with a laterally extending base xflange 14. The upper portion or head 15 is formed with a laterally extending flange 16 and provided with a longitudinal vertically extending groove 17.

The-intersecting and extension portions of the crossing sections are particularly formed for detachable engagement with removable intersecting heads or frogs 18, the detailed structure of which will be described more fully hereinafter. Thisportion .of the crossingstructure is designed to providea ahead supporting -base an d-consequently cut down for this purpose. With this in mind.v the base web 13 is formed -.with.a flat horizontal face 19 immediately below the head of the rail and provided at .theccnter with a longitudinal vertically arranged (groove 20. Formed transverselythrough the upper portion of the web 13, so .as to intersect the groove 20 formed .therein, is .a plurality of openings .21 the ,purposeof which-will-become apparent as the description progresses.

he intersecting heads or'irogs 18. illustrated to advantage in Figur. are formed of a pair of intersecting rail sections 22 embodying a web portion 23 similar in formation to the web 13 of the crossing base structure and having a longitudinal groove 24 formed on the head portion conforming in. shape and arrangement to the grooves 17 formed on the crossing rail sections and adapted to align therewith. Formed on one side of the head portion is longitudinal.

Ill

flange adapted to be arranged in horizontal alignment with the head flange 16 formed on the crossing rails. The lower face of the Web 23 carries, on the center thereof, a vertical longitudinally extending reducing web 26 adapted to snugly engage the grooves 20 formed in the base section of the crossing. These webs 26 are provided with transverse openings adapted to be aligned with the openings 21 formed in the crossing base to receive therein fastening bolts 27, for secure connection of the frogs upon the crossing structure. The particular structure of the intersecting heads or frogs, as illustrated, embodies comparatively short inner rail extensions and longer outer eX- tensions engageable with the base sections.

In assembling my improved crossing structure, the frogs 18 are positioned upon the intersecting portions of the crossing base so that the reduced flanges 26 engage the grooves 20 formed in the crossing. In this position, the shorter ends of the frogs will be fitted to snugly abut the adjacent ends of the crossing rail sections. The fastening bolts 27 are then inserted through the aligned openings and secured against displacement by nuts. Thus, the frogs 18 will be securely fastened upon the intersecting portions of the cross ng structure and firmly supported. From Figure 6 of the drawing, it will be seen that the lower faces of the frog webs 23 will be firmly seated upon the upper faces of the crossing base webs 13 so that the sides thereof will be arranged in vertical parallel alignment.

The usual rail sections may then be connected to the extending portions of the crossing sections by suitable rail joints of any preferred design. The primary char acteristic, however, is the provision of the durably titted detachable frog construction capable of rapid replacement. The wide contacting surfaces of the base and rail web structures provide a very durable rail and produce a very etlicient and practical struo ture.

It is to be understood that the form of my invention herewith shown and described is to be taken as the preferred example of the same and that various changes as to the shape, size and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.

Having thus described my invention,l claim:

1. A railway crossing structure comprising a crossing frame having rails formed at the intermediate portions and grooved base sections formed at the intersections, the said base sections each including a vertical web portion, base flanges formed on the lower edge of the web portions, and longitudinal grooves formed on the upper faces of the webs, and'intersecting rail heads removably engageable with the base sections including intersecting body webs having rail grooves formed on the upper surface of the webs, and areduced web formed on the lower surface of the body web engageable with the grooves formed in the base sections.

2. A railway crossing construction comprising an intersecting crossing frame having integral rail heads formed at the intermediate portion and grooved spaced sections formed at the intersecting portions, and intersecting rail heads ren'iovably engageable with the intersecting base sections including body web portions formed on their upper side with flanged engaging grooves, and a reduced longitudinal web formed on the lower side of the main web portions adapted to engage the grooves formed in the intersecting base sections.

3. A railway crossing construction comprising an intersecting support frame including vertical web portions formed with intersecting grooves on their upper edges, supporting flanges formed on the lower edges of the webs, detachable heads removably engageable with the support frame including main web portions conforming to the structure of the frame webs having rail engaging grooves formed on the upper edges, a laterally projecting flange formed laterally at one side of the main web portions aligned with the upper surface thereof, and a reduced web formed verticallyon the lower edge of the main web portions removably engageable with the grooves formed in the support web for detachable connection of the intersecting heads.

In testimony whereof I atlix my signature.
